For a minute there I thought you were going to leave us hanging by not proping up that harness and starting the vehicle. If you didn't I was going to complain loudly. As always great job, I learn alot and your skills are amazing.
Nice straight forward diagnosis. That’s the nice part about diag work you can point to what needs to be fixed and not have to struggle with the repair. 😂
A-1 job. Making it look easy for sure. Simple basics win out all the time, step by step perfect working diagnostic. So many get overcome by making it seem harder then it is. Great job.
Jake, great video and great find. Kind of motivates me to crawl under my van to find the squealing whiny noise that I think may be related to a code that is being thrown. I just don't know if I have the patience that your have. Thanks for Sharing!
Now that was very interesting. Especially because I have a 2002 S10 with a short to my right side horn. Have not looked hard for it because the harness is also buried, between the rad and ac but now I am more enthused to look. Will also look at your how to find a short video. And I have a bore scope but it never entered my mind to use it. Now I will. Thank You.
Great thought process! I also thought of the borescope, to go into such a tight place, and then you go and get it :-) This was easier to spot than it will be to repair. Excellent ending too :-)
Another job made look easy your knowledge of troubleshooting and knowing your circuits and experience over the years if you take your time to work these sensors and actuators it makes very informative watching and learning Quality teaching .Cheers😂
Great work bro i get new idea from your video; from what I usually will do is check the wire continuity/resistance test from sensor connector to module connector and check for short to power or short to ground. Now I got new idea by watching your video nice work👍👍
You’re the electronics guru I was chasing a p2138 app 1 and 2 not plausible. On a 2015 Tahoe shop replaced app and pigtail. Only happens intermittently. Only thing I’m suspicious of is the 3 connectors the signals go through to get to the pcm were packed full of dielectric grease including pcm connectors. You ever see issues using dielectric grease on sensitive circuits like app and throttle body etc. I cleaned it out been driving it for 4 days no issues. Wiggled wiring harness etc heated pcm up with heat gun no failure. Only thing I can come up with is the grease
*Another great video. I now know how to check short to ground. I wished you pulled the harness away from the bracket and see if the car starts but what you showed so far is good enough fo me. Thanks.*
Great video and use of Specialty tools so you get the job done. I blew the bulb and my old kent More test light a few years ago, Have you found a place that you can buy the bulb Without paying half the price of a new test light, I actually now have lost the bulb and don't know what number it was,,,, GM Advise us to use them when checking PCM's back in late eighties, Yeah I'm old.., in fears of burning out a trace circuit in the module, But I have used an old Kent More / OTC noid light, 'the old incodessing one's' Or a 194,, These old Kent More test lights were low Impedience But I don't remember how many amps they will actually draw, Do you know this right off hand
Jake, couldn't you make one of those test lights using two reverse parallel LEDs with two 220 ohm resistors in series with each LED? Just put the works inside an oil sample vial with 2 test leads coming out of vial?
I have a 2012 Wrangler JK, camshaft position sensor bank 1 keeps popping up and the engine goes into limp mode, I replaced the sensor with an oem Jeep part but still have this problem, along with an intermittent stall or shut off of the engine at very low speeds like pulling into a parking space or going through a drive-through, the engine cuts out. I'm thinking it might be some wires that are exposed or rubbing, no code when the engine stalls, have to put it in neutral turn the engine off and then restart, it's getting frustrating.
Took the Jeep out for a ride again this morning, on the highway it's hauling arse, but when I was on some surface streets and pulled into a plaza it's stalled then the code popped up again. Going to take it to my mechanic and see if he can walk things back to see if there's a short in the wiring somewhere.
if you had left it un plugged, would it have started off the crank sensor ? or would the short still kept it from starting ? I know some code tell u circuit high and circuit low ,can u use those codes to help indicate a open or short ?

These cams pick up is magnetized. If you put a magnet next to the pick up on the cam itself it will lose its ability to produce the correct signal. Ask me how I know. 😂
@@autodiagyt i found it had been a few days since i watched it. just so happens this guy had the same short in the same place as yours after looking again could tell completly different video its odd to find 2 videos with the same problem in the same place
a test light in a dc circuit has resistance not impedance. im·ped·ance /imˈpēdns/ noun the effective resistance of an electric circuit or component to alternating current, arising from the combined effects of ohmic resistance and reactance. sorry my nerd is kicking in.

Your great at what you do and your a great teacher I always learn something every video
That was a pleasure to watch . I do this stuff everyday problems are usually in terrible places . Great video

No parts required fix. A very good quality video and edit!

Well, if they don’t rely on that harness, then he’ll be back in the winner for some more work
@@robertmedina6875 Yep 🙂

First I love your shades and second I love watching you work!! Great job!!!
Great info superbly diagnosed and perfect repair.cheers
Jake you never disappoint, Great video!! I got to check out this low current test light.
@@autodiagyt Wow I've never seen that happen I use a 194 bulb, but I make sure the module is unplugged. Can you leave a part number please?
@@autodiagyt Thank you! I just ordered it😄
spot on Jake - I saw a vid by Ivan about a year ago where he smoked a door module with regular test light@@autodiagyt
Great diag process from start to finish along with a tool review! Thanks for sharing with us!

That’s what I been doing. Still waiting on it to act up
Looks like Is the right time to check if the engine oil cooler/ filter housing is leaking and replace it at the same time
Great technique! Nice testlight!
Great video again.troubleShooting at it's best
Great video! Very informative! Thanks again!!!
Solid work bro. Keep it pushing. Loving the videos
Fantastic Jake!
thanks for sharing.
Excellent troubleshooting

Sweet shades man! Great video
Take intake off? How about run new wire from engine computer to sensor? That would probably take less than half hour
Where did you get those piercing probes when you tested cam signal?
Great job man! 👏
I like your eyes! But also awesome work on this!!!
Nicely done
I like your thought process I’m in England and work mobile and we have a multitude of different types of jobs like you do nice work geezer 👍

Great job Jake, I'm in favor of dividing the circuit in half for testing when ever possible.
what state is your shop in? im in okc
Heard you refer to Snap-on scan tool data quality as your go to tool over others, could you elaborate?
if you had left it un plugged, would it have started off the crank sensor ? or would the short still kept it from starting ? I know some code tell u circuit high and circuit low ,can u use those codes to help indicate a open or short ?
awesome video Jake thanks man
I wonder if we can make our own high impedance test light. :). Thanks for posting these electrical diag videos, very helpful!
Awesome find!

great video tks
Awesome diag got my subscription 👊🏻

👍👍👍
Hard time finding that test light . Think I got last one 👊🏻
good work!!
Nice 👍
I’m having this problem! Help

I am pretty sure saw this same video on another channel voice different never showed face same vehicle same camera same spot on engine.
@@autodiagyt i found it had been a few days since i watched it. just so happens this guy had the same short in the same place as yours after looking again could tell completly different video its odd to find 2 videos with the same problem in the same place
